Mild and moderate COVID-19 disease does not affect hearing function permanently: a cross-sectional study ınvolving young and middle-aged healthcare givers

Purpose To assess the hearing function of patients with mild and moderate COVID-19. Methods The hospital staffs recovered from COVID-19 were included. The candidates who had an ear disease or progressive hearing loss prior to COVID-19, or having been hospitalised because of severe and critical COVID-19 were excluded. The age, sex, symptoms during COVID-19, and medications received for the disease were noted. The hearing thresholds (HT) of the participants who had an audiogram before having COVID-19 disease were recorded. A pure tone audiometry was conducted to all. The participants were classified into two groups; Group 1: participants who had an audiogram previously, Group 2: participants who didn’t have an audiogram previously. The changes of the HTs of the participants in Group 1 were analyzed. The HTs of the participants in Group 2 were documented without any comparison. The HTs of all participants were also analyzed by classifying them into subgroups according to their symptoms during, and medications received for COVID-19. Results Fifty-four males and 47 females (18–59 years) were included. The participants’ HTs in Group 1 ( n = 31) did not change significantly at any of the frequencies after having COVID-19 ( p > 0.05). The pure tone averages of the participants in Group 2 ( n = 70) were below 25 dB and none of the participants reported worsening of their hearing permanently. The differences between the HTs of none of the subgroups were statistically significant ( p > 0.05, p > 0.05). Conclusions Mild and moderate COVID-19 and its treatments did not affect the hearing function permanently.
